Number of deretraction moves (zero-length moves with negative E)
Cumulative newly advanced filament length in millimeters, including E-only purges and primes. Recovery of previously retracted filament is excluded; retracting never subtracts filament already consumed.
Number of bare feedrate changes (F with no movement)
Number of zero-length moves that were neither a retraction nor a feedrate change
For reference, how many points were added to the job
Number of retraction moves (zero-length moves with positive E)
